What made Constantinople such an important city to conquer for the Ottoman?

‘Rebirth’ was the result of the near death experience of Islamic civilization during the Mongolian invasion in the 13th century. This ‘great catastrophe’ was the culmination of a long series of foreign and domestic attacks resulting in millions of deaths, demolition of Muslim urban centers, destruction of irrigation systems crucial for agriculture, burning of libraries and the ancient cultural heritage of Mesopotamia and Persia, and most importantly the failure of Islamic unity, the cornerstone of the Muslim project. In light of this tragic upheaval, we can understand the urgency felt by Muslims to try to understand what went wrong and how to rebuild. Two drastically different responses to this tragedy emerged; a radically conservative reaction championed by the Ibn-Taymiyya, calling for a return to the religious ways of Mohammed and his companions and a progressive and novel approach built upon the fusion of Sufism and Turkish nomadic traditions. Out of the latter a new world empire will unfold, namely the Ottoman Empire.Anxiety in Muslim societies was felt as early as the 11th century. This anxiety, born out of a sense of instability, was fueled by the relative failure of Islamic unity, the struggle against the crusaders conquest of the holy lands, the ferocious and destructive invasions of the Mongols, and the Assassins’ terrorism. How did these different events spark a crisis for Muslim theology? Elaborate on the conservative response to this “identity crisis”…

One of the more popular and progressive responses to this crisis was the development of Sufism. How did this spiritual movement end up in Asia Minor (Anatolia) along with Turkish nomads from central Asia and how did their fusion lead to a major political and military conquering force?
